Types of replacement windows we offer

After 30 years of expert installation in Northwest Indiana and Illinois, we’ve installed nearly every type of window you can imagine. The most common styles we work with include:

Double Hung Windows Installation & Replacement Northwest Indiana

Double Hung Windows

Double-hung windows feature two moveable tilting sashes for efficient ventilation and easy cleaning. The sash is the portion of the window that surrounds the glass and holds it in place. Our vinyl double-hung windows offer many benefits.

  • Low-maintenance, energy-efficient windows that will never need repainting.
  • Enhanced safety, including a frame that is 52% stronger than a standard vinyl frame. 
  • Tamper prevention features that exceed even the most stringent requirements to protect against forced entry.
Single Hung Windows Installation & Replacement Northwest Indiana

Single Hung Windows

A single-hung window features one movable bottom sash and a stationary top sash. Single-hung windows offer many eco-friendly features. Our single-hung windows are perfect for your home or business.

  • A unique tamper prevention system and 52% stronger frames than standard vinyl protect your home from intruders or forced entry.
  • No painting or refinishing is necessary, with solid color throughout the vinyl for long-lasting beauty.
  • Energy-efficient options and exclusive weather repel system helps channel water away.
Slider Windows Installation & Replacement Northwest Indiana

Slider Windows

In a slider window, the sash slides horizontally (left to right) to open or close. We proudly install a variety of sliding windows, including 2-lite and 3-lite slider windows.

  • Low-maintenance sash rollers offer years of smooth operation and efficiency.
  • Triple-pane glass windows are over 60% more energy efficient than single-pane windows.
  • Automatically locking hardware is standard on these windows, providing greater security.
Casement Windows Installation & Replacement Northwest Indiana

Casement Windows

Casement windows feature a hinge on one side of the sash, and the window is opened or closed using a small hand crank at the bottom of the frame. We often install casement windows in hard-to-reach places where a tilting or sliding sash would not be practical.

  • Durable, maintenance-free vinyl stands the test of time.
  • A wide selection of colors and styles is available.
  • Dual- and triple-pane windows available that are up to 62% more energy efficient than single-pane ones.
Awning Windows Installation & Replacement Northwest Indiana

Awning Windows

Windows that are hinged along the top and open outward from the bottom are known as awning windows. We install vinyl awning windows in many shapes and styles.

  • The multi-chambered frame is over 50% stronger than traditional vinyl.
  • Easy to care for and fade-resistant.
  • Adds a unique look to your home or business.
Picture Windows Installation & Replacement Northwest Indiana

Picture Windows

Picture windows are non-operable, meaning they’re sealed shut. Often larger than other windows, they offer stunning views combined with considerable energy-efficient features. 

  • Available with many popular features, including grilles between the glass, triple-pane glass, and a variety of exterior colors. 
  • Efficient against weather, picture windows prevent warping and twisting with precision welded frames.
  • Strength enhanced, our picture windows are up to 52% stronger than standard vinyl.
Bay & Bow Windows Installation & Replacement Northwest Indiana

Bay & Bow Windows

A bay or bow window is a window that protrudes out from the exterior walls of a home or building. Bay and bow windows are typically made of three sections, with a fixed window in the center and two operable windows on either side. The operable windows can be opened to allow for additional natural light and airflow. The fixed window provides panoramic views and depth to the room. Bay and bow windows are an excellent way to maximize interior space and create a more open feel to a room.

Special Shaped Windows Installation & Replacement Northwest Indiana

Special Shaped Windows

Specialty windows are windows that are not a traditional shape and can come in a variety of shapes and styles. Special-shaped windows can add charm and character, enhance curb appeal, add more light to a room, and highlight an architectural feature of your home. Special windows are an excellent choice if you want to match a specific design or style or make a visual statement. Contact us to explore your options for window replacement with our window experts!

An average house has 10-25 windows of all shapes, sizes, and compositions, and a large window replacement job may take 2-5 days. Most door installations, on the other hand, can be completed same-day. Give us a call to discuss the specifics of your project and get a more accurate timeline.
